Satellite TV is a wireless broadcasting service. Satellite communications use antennas to transmit and receive radio signals to and from satellite dishes. Most satellite TV use direct broadcast satellite (DBS) provider.
Early satellite TV broadcast on the C band radio at 3.7 – 4.2GHz downlink and 5.925 - 6.425GHz uplink. Digital broadcast satellite transmit programming on Ku band frequency range (11.7-12.7GHz downlink and 14 - 14.5GHz uplink) and Ka band uplink 27.5GHz and 31GHz, and downlink 18.3GHz & 18.8GHz and between 19.7GHz & 27.5GHz.
Satellite TV providers on earth collect various programs and a broadcast center converts programming into high quality digital and sends it to a satellite in geosynchronous orbit. The satellite receives the signals and rebroadcasts them to earth. The viewer's satellite dish receives the analog and/or digital signals from the satellite (or multiple satellites in the same part of the sky) that reach the home and they are amplified, filtered and sent the viewer's TV. A receiver de-scrambles the encrypted signals and also sends signals to disrupt illegal de-scramblers (electronic counter measure (ECM). It also keeps track of pay-per-view programs and periodically contacts the provider's headquarters regarding billing information.
